The deference between α-Arbutin and β-Arbutin

Chinese Name α-Arbutin β-Arbutin
INCI Name Alpha-Arbutin Arbutin
EU-Labeling Name Alpha-Arbutin Arbutin
Chemistry 4-hydroxyphenyl-α-D-glucopyranoside P-hydroxy phenyl - β -D- glucopyranoside
CAS No. 84380-01-8 497-76-7
EINECS No. 440-470-8 207-850-3
Melting Point 198-201oC 198-201oC
Specific rotation (a)20D=+174.0-+186.0 (a)20D=-66-+2

Different Efficacy and Safety
ALPHA-ARBUTIN exhibits impressive in-vitro tyrosinase inhibition on human cell lysates compared to Beta-Arbutin. According to the test result from Inhibition Test of Tyrosine and B16 cell, it indicates that ALPHA-ARBUTIN has 10x more effective than β-Arbutin.
Commonly, the dosage to use β-Arbutin is 3% for cosmetic. If reducing the dosage,skin lightening effect is much less. But rising up the dosage will bring in irritation on skin. Contrarily, ALPHA-ARBUTIN exhibit impressive in-vitro tyrosinase inhibition on human cells, which brings in superior skin whitening efficacy without side effects.


Different MFG Methods
There are 3 ways to produce β-Arbutin including botanical extract,plant cell cultures,chemosynthesis. ALPHA-ARBUTIN can be only produced via Biosynthesis.
Luckerkong Biotech adopts advanced international biotechnology to make ALPHA-ARBUTIN, offers higher quality and stability.
